. My invention relates to devices that may be adapted to use in prolongingthe fresh state of eggs, an object being in this desire not only to accomplish this result in a simple and economical manner but to ;do it in a Way that will enable those who are. taking car-e of eggs in storage in large quantitles to take care of a great many eggs at a time.

invention embodies a design and con struction of egg preservers that is adapted to accommodate eggs in :big quantities for storage and preservation and it will he .t'ound that my device combines the merits of strengtli and practical utility in the purpose for which it is designed, my device will keep eggs 4 to .6 weeks for hatching .or a year inwholesome condition for tood purposes.

particular .obj ect of my invention thereore is to provide an egg preserver which in its construction includes means for turning the eggs periodically and all simultaneously, it being the preferred and intended purpose of the invention to have the device in operation within the confines of cold storage compartments. 1

Before attempting to point .out the detail of construction and operation of my inven.- tion it may be well to explain the fact that the yolk of an egg'is. heavier than the white albumen that supports it and when an egg lays on one side for an extended periodpi' time the heavier weight of the yolk causes itlto settle down through the albumen until it comes in contact with the inner .surtace ofthe shell Where it is subject to exposure to a [certain amount of air which comes into the egg through the porous shell. Since the yolk of .the egg .is the fertile part .of the egg and the albumen merely adapted to the protection of the yolk and since by laying in one position the yolk settles through the albumen and comes into contact with the shell and becomes exposed itis evident that in this way the yolk is subject to becoming spoiled and for food and unwholesome.

It is to prevent the yolk from settling through the albumen until it comes .in Icontact with thejshell that my device .is adapted to operate and is particularly adapted to operate in rendering such careful protection to many eggs at a time.

it is 'a particular purpose of this egg prepurposes abecoming. foul server to provide a imeans whereby .theeggs contained on the rack maybe rolled approximately half-their circumference so that a tiltmg of the rack causes these eggs which arastored .on trays to be .ti-lted from one position to another to accomplish a rolling of eggs so that the yolk "therein on one dayhes with its weight .urgingv in one directlon against the li uid albumen within the shell and the next. ay the egg is turned and the yolk is turned so that its weight is rempved from the former position and rests against another partof the albumen. Thus it will be seen that by a periodical change of position for the egg my device preserves the eggand prevents the yolk from coming into contact with the shelland in doing so 1s adapted to accommodate a plurality of eggs on a plurality of trays for convenience and economy in operation.

7 Another object oft'my device is to provide a ltlltingegg preservermounted upon a rigid frameand having means for accomplishing the optional tilting-ct the rack to any desired angle .or degree Within predetermined tl-ltingl'irnit.

The above and other .objects will become apparent in the description below in which characters of reference denote like named Parts in itheseyeral drawings.

Figure 8 is a cross sectional view of Figure 7.

Referring in detail to the drawings, nu-

1neral--10- indicates a rigid horizontal platform on which the entire device is adapted to be mounted This platform is supported at its corners on legs 11- and at its side edges intermediate its length on a pair of posts 12 and 18 which extend vertically upward for the support of the rack that is adapted to support the eggs when tilted. At the upper and lower ends of the posts ,12- and 13-+ a shaft -14.

and 1 is anchored in said postsand adapted to span" the distance between the two posts. Upon these shafts'the entire egg carrying rack is mounted. This rack V -18 thus forming an integral rectangular consists of a plurality of angle irons 15-- and --l6 which constitute the side-framing members of the rack and are rounded and loosely joined at their ends to vertical corner rails'.-17. These angle irons are so positioned as to present ledges which extend mutually toward eachother to provide -a raceway or support upon which the egg trays are adapted to be supported.

The width of the space between thecorner rails 17 at the ends arejoined by iron rails skeleton frame upon which the egg trays are stored for any desired length of time. The bottom angle irons 16- and -'17 are spanned by a plate 19' which is riveted to said angle irons at a predetermined posi-' tion on one side of the posts 12 and '13 and is provided with a pivoted boss 20 which is adapted to loosely and the distance between brackets 21+ and 22-' and has its ends journalled in said brackets; andv collars'are provided to rotatably fix said bar in position on said brackets. -This bar'has a pair of arms.

24- and 25- extending downwardly through which a pair of aligned holes are formed. These aligned holes receive a shaft -s6 which is rotatably mounted therein.

and has at its inner end a beveled gear -27 secured therein.

Intermediate the lengthof bar -28+,"an annular ring 28 is formed throu h which a restricted portion 29 of the the shaft 2G.

tilting screw 30-- passes. The upper end of the tilting screw is threaded throughout its length from the restricted portion 29- V to its outer'end which projects upwardly.

The lower. end ofthe tilting screw is not provided with threads and extends downwardly beneath the bar 23 from the restricted portion -29 and has mounted on its lower end a beveled gear 27* which is adapted to lie in continual mesh with the beveled gear 27- mounted .on The outer end of the shaft '-T26 passes through an arcuate slot 32 formed within avertical guide: plate and has mounted thereon a! crank handle 3t' which when rotated causes the gear 27- to rotate the'tilting screw to the medium of the gear 27f.

Figures 5' and 6 illustrate the simplest type of device that has. heretofore been known to be used for turning eggs in numbers. This'simple form consists of a boxlike structure having a bottom 35--and' side walls 36 which are joined at their ends with end walls 37- and -38; the end wall -38 being lower than the opposite end wall .-87. Betweenthe end walls 37 and -38 an inclined platform 39- is provided, said platform extending and rising gradually upward to a position near the upper end of. the highest end wall On this platform, a pair of semi- 37.. oval grooves 40- are formed which extend lengthwise on the platform throughout its entire length.- Into these grooves, eggs l1 are adapted to be placed.

Figures 7 and 8 represent the type of egg tray used with the device illustrated in Figure 1 and is supported upon the rails 16...

This tray comprises a relatively flat longitudinal board .42 having a rim'43- bounding three sides thereof. At spacedapart positions of the board,.longitudinal channels -44- are formed.

greatest dimension at the bottom of the channels 4ll. Adjacent each of these channels, a semi-oval. groove 4:5 for holding the eggs deposited therein by the care taker. These eggs are placed in the trays from the marginalwall 47 outwardly and are retained in place thereon by stop plates 4" which have studs 48- at one end, said studs being of the same fitting dimensions andsquare in cross section as the channels ---44 within which they register.

It Wlll be observed that arrangements are providedin the structure of this rackfor conveniently handling the egg trays in and out of the rack and it will also be observed that an arrangement is provided for slidably admitting the egg trays to the rack and holding the same detachably secured therein.

At one end of the racltthe members 18-.-.-

Frame members +157 and 7 are adapted to be pivotally and looselyengaged with upright members 17' at their respective ends; said frame members in their pivoted condition being rounded on the end to easily permit a rotating or tilting movement.

By having frame members -15 and 16 loosely and pivotally engaged with the upright members 17- it will be observed that when the rack supporting the egg-trays is tilted that the upright members -17 will always remain in an upright or vertical position thus providing a perfect balance for the rack in all angles of its tilted position and it will be especially observed that by providing this convenience that there will be no sudden tilting or change of speed in the rate of tilting which might unfortunately cause trouble in handling big quantities of eggs; for the reason that it is very desirable to handle eggs quietly and carefully and avoid any unnecessary jars or shocks of any kind.

The device is used in the following manner: Eggs -4G are loaded on the tray 4l5 so that a space exists at one end of the tray which will permit the movement of all the eggs upon the tray a distance equal to half their circumference when the loaded end of the tray is tilted upwardly. The loaded egg trays are deposited upon the rails 15 and -16. The tilting rack is supported and balanced upon the shaft -14- and 14- which permits an equal angular movement of said rack on both sides of the posts 12 and -13-. This rack is tilted by rotation of the crank -34- which causes the shaft 26 to be rotated; and this shaft having a gear 27- thereon, which is in mesh with the gear 27 on the bottom of the tilting spindle rotates the latter. This tilting spindle meshing in the boss on plate 19 fixed beneath the rack and across it near one end thereof causes the rack to be moved upwardly or downwardly according to the rotation of the crank and thereby tilts the rack from a positien sheen n u e l o el esi e xtreme tilted-position in which the corner postson the right hand side ofFigure 1 lie in contact with the surface of platform With reference to the lifting or tilting movement of the rack attention is called to the fact that boss which threaded is adapted to register centrally with theap erture +49- in plate1) (see Figure 4, 7;"

Plate l 'Boss 20 is pivoted by spindles 50-- and supported in normal position by bearings. -51 It will be noted that this construction eliminates any chance of thread binding during'the lifting operation when the boss 20 rides the threaded lifting SQI'BW TV3O The tray platforms 42.- will slideupon Y that a space equalto the circumference of the eggs exists between the stop plate and the outer egg of a row. These stop plates are prevented from rotating by pro viding studs l8 square in cross section so that when said studs are inserted into the grooves 4:4: these studs are held in place by friction. WVhen the tilting rack is tilted from one position to another, the eggs will roll toward the stop plates -4:7 or toward the retaining wall 47 according to the direction of the tilt of the rack. The

rack when in the act of being tiltedwhen loaded with trays causes the eggs 4L6 on the trays to roll toward the tilted end of the trays. The first row of eggs adjacent to space begins to roll into the spaces on the tray and the successive rows of eggs follow i the first row in rolling toward this space, thus turning the eggs. The yolk which tends to settle toward the the albumen which is lighter than the yolk will then be rotated to a position that will permit its weight to fall back to the center of the albumen surrounding the yolk thus preventing the yolk from settling through the albumen to reach the egg shell which would'expose the yolk to air through the porous shell.

In the simple type of egg transferring trays illustrated in Figures 5 and 6, the eggs will be deposited in the grooves 40 in the manner shown in Figure 5. When it is desired to roll these eggs, the lowermost egg 48 on the inclined platform 39 is lifted from place, thus permitting the entire row of eggs to roll downwardly on said platform for approximately one half of their bottom through ISO circumference so that the yolk which previously settled-toward the bottom position the platform 39- isthen deposited by hand at the top of the row of eggs, care being taken preferably that in moving this egg its position also be changed to protect it in the same manner.

To those skilled in the art to which the proper care of eggs pertains it will be evident that the method of preserving eggs by such periodical changes in rotated position will be effective, but in the device of my invention I propose to accomplish such results in the preserving of eggs in a manner that will enable the operatorto care for 21 plurality of eggs at a time the number being limited only by the quantity desired tobe taken care ofand the practical sizes of racks. v

Having thus described the nature of my invention what I claim as new and useful and desire to secureby Letters Patent is: A device of the class described comprisin a platform, posts thereon, a shaft journalle on said posts, a rack balanced intermediate its length on said shaft, trays adapted to be supported'on said rack, means for tilting said rackcomprising a plate mounted on said rack, a tilting screw engaginga pivoted boss centrally disposed'on said plate and rotatably mounted on said platform, and means for rotating said screw.

In witness whereof. I hereunto set my hand this 13th day of June, A. D. 1925.
